Jack of Hearts vs. Deathlok:
Jack's Bio:
Jack of Hearts possesses the ability to project concussive energy from his body. This energy, a by-product of the cellular mutation caused by contact with the experimental Zero Fluid, is generated in some as yet unknown way by the cells of Jack's body and can be directed in controlled amounts by conscious thought. Zero energy, as it has been called, is constantly being generated by his body and is emitted in negligible quantities whenever his cells reach their saturation point. Consciously directing the flow of energy (usually through his hands), Jack of Hearts can create a shock wave, the current maximum force of which is unknown. The energy discharge is accompanied by a pink colored light phenomenon.
Jack of Hearts' entire metabolism has been transformed by the Zero Fluid's mutagenic effect on him. Not only does he require less oxygen, but he is physically stronger and more resistant to injury. Jack of Hearts can easily withstand small-caliber firearms. Further, if he is injured, his rate of healing is over twice that of an average, healthy human's.
Now that Jack of Hearts' powers have increased exponentially, it is difficult to gauge what his current abilities and overall power level is.
Deathlok:
Luther Manning's mechanical, cybernetic physiology granted him several superhuman powers including superhuman strength, stamina, agility, reflexes, and a computer augmented brain.
Michael Collins' cyborg body grants him the same powers, only with much greater strength, speed, and resistance to injury. His body can also target (nearly infallibly) multiple objects and track them. He could scan the entire electromagnetic spectrum, as well as enter computer systems.
The Michael Collins Deathlok has learned to use internal nanobots to repair and alter both his organic and inorganic parts, enabling him to appear as either a humanoid cyborg, or completely human.
The Michael Collins Deathlok also has a very sophisticated A.I., capable of quickly making complex strategies and evaluating their chance of success. If requested, the A.I. can take control of the body to perform these operations.
This is a very good match-up. Both characters could probably gain an abundance of information on each other and both wouldn't want to go for a kill-shot in order to win this match.
I think this will basically be a last man standihg type match, where the first one to fall (without being killed) will end up being the victor. That advantage, in my opinion (of course), goes to Jack. He's gone toe-to-toe with the Incredible Hulk, withstanding his massive blows, and actually coming out the last person standing. For Deathlok, he can regenerate himself, but he must be able to have time to do it. It will be a knock-down, dragged-out battle; but, if Jack can withstand numerous punches from The Hulk, I'm betting he can withstand what Deathlok throws at him. Also, having the power of flight at his disposal, Jack of Hearts can more easily stay out of range of Deathlok than the other way around.
Finally, another bio of Jack explains some things a bit better.
He was also capable of absorbing energy from other sources. He possessed superhuman levels of healing and endurance and could survive unprotected in space. Although he only had normal intelligence, his thinking capacity was enhanced by a scanning device which gave his thought processes the speed and efficiency of a highly advanced computer. Jack also had superhuman strength.
Abilities Jack is a trained S.H.I.E.L.D. agent, the extent of which is unknown.
It shows that Jack is trained by S.H.I.E.L.D. and has the thought processes of a "highly advanced computer." Plus, his ability to absorb other forms of energy might make some possibly weapon choices of Deathlok null and mute.
Winner = Jack Of Hearts
